Maximum Tolerated Ratings
This section provides the maximum tolerated voltage and temperature ranges for the MPC852T. Table 1 provides
the maximum ratings and operating temperatures.
This device contains circuitry protecting against damage that high-static voltage or electrical fields cause; however,
Motorola recommends taking normal precautions to avoid application of any voltages higher than maximum-rated
voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an
appropriate logic voltage level (for example, either GND or VDD). -- VDDH.

Functional operating conditions are provided with the DC electrical specifications in Table 5.
Absolute maximum ratings are stress ratings only; functional operation at the maxima is not
guaranteed. Stresses beyond those listed may affect device reliability or cause permanent
damage to the device.
Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than VDDH. This restriction
applies to power-up and normal operation (that is, if the MPC852T is unpowered, a voltage
greater than 2.5 V must not be applied to its inputs).
